Optical Performance
The Cisco SFP-OC3-LR2 is designed for extended-distance OC-3/STM-1 optical transmission. Cisco specifies a 1550nm SMF interface and a maximum cable distance of 80km over G.652 single-mode fiber.
Long-Distance Fiber Connectivity
The LR-2 designation identifies this module as the long-reach 80km variant within Cisco's OC-3/STM-1 SFP family. Its 1550nm optical transmission makes it suitable for long-distance telecom and service-provider fiber infrastructure where extended optical reach is required.
Applications
- OC-3 SONET network connections
- STM-1 SDH optical links
- Packet-over-SONET/SDH (POS) applications
- ATM optical networking
- Long-distance telecom fiber links
- Service-provider network infrastructure
- Inter-site optical connectivity
- Legacy SONET/SDH network expansion and maintenance
Compatibility
The Cisco SFP-OC3-LR2 is designed for Cisco platforms that specifically support the OC-3/STM-1 LR-2 SFP. Cisco documentation lists the module among qualified optics for compatible OC-3 ATM and POS interfaces, including Cisco 7600 and CRS platforms.
The module uses a dual LC/PC optical interface and G.652 single-mode fiber. Verify the exact host platform, software support, optical budget, and remote-end optic requirements before deployment.
